I-CBP112 is a selective inhibitor of the bromodomain-containing transcription factors. I-CBP112 (1 mM) has little activity against other bromodomains. I-CBP112 targets the CBP/p300 bromodomains. I-CBP112 significantly reduced the leukemia-initiating potential of MLL-AF9(+) acute myeloid leukemia cells in a dose-dependent manner in vitro and in vivo. Interestingly, I-CBP112 increased the cytotoxic activity of BET bromodomain inhibitor JQ1 as well as doxorubicin.

| Description | I-CBP112 is a selective inhibitor of the bromodomain-containing transcription factors. I-CBP112 (1 mM) has little activity against other bromodomains. I-CBP112 targets the CBP/p300 bromodomains. I-CBP112 significantly reduced the leukemia-initiating potential of MLL-AF9(+) acute myeloid leukemia cells in a dose-dependent manner in vitro and in vivo. Interestingly, I-CBP112 increased the cytotoxic activity of BET bromodomain inhibitor JQ1 as well as doxorubicin. |
| In vitro | I-CBP112 markedly increases acetylation by p300 at the histone H3K18 and H3K23 sites. I-CBP112 stimulated H3K18ac by ~3-fold, and induced enhances acetylation of these same sites by CBP as well as at H4K5. The EC50s of activation of I-CBP112 on CBP- and p300-mediated H3K18 acetylation are ~2 μM[1]. In mouse and human leukemia cell lines, I-CBP112 causes substantially impaired colony formation and induces cellular differentiation without significant cytotoxicity. In BioMAP primary cell panel, I-CBP112 results in a unique response on cytokine and marker protein expression[2]. |
| In vivo | I-CBP112 markedly and dose-dependently reduces the leukemia-initiating potential of mLL-AF9+ AmL cells in vitro and in vivo. The synergistic effects of I-CBP112 and current standard therapy (doxorubicin), as well as emerging treatment strategies (BET inhibition), provide new possibilities for combinatorial treatment of leukemia and potentially other cancers[2]. |

DMSO
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
